Colitis
Colitis is a common problem in cats and like constipation, can have numerous causes. Some cats develop food intolerances and even food allergies that stimulate the colon tissues to react. Chronic bacterial infection can play a role in colitis; too many of the wrong kinds of colonic bacteria can initiate an inflammatory response. And just as in human medicine, there are types of colitis in the cat that seem to be spontaneous and often require specialized techniques for an accurate diagnosis to be made. Even autoimmune disorders can affect the colon when the body's own defenses attack the colon tissues.
